Ensuring reliable Water Management for Africa’s largest Oil Refinery, Securing the resources needed to support economic growth and development.

WABAG has successfully executed the contract for the comprehensive water treatment system for the new Grass Root Petroleum Refinery and Petrochemical Complex of the DANGOTE Group in Nigeria, the largest industrial conglomerate in West Africa. The 650,000 BPSD refinery is located in the Dangote Industries Free Zone, Lekki, Nigeria.

The scope of works included:

• Raw water intake and raw water treatment
• Demineralisation and condensate polishing unit
• Effluent treatment and recycling plant.

WABAG has designed a multi-stage treatment employing state-of-the-art technologies like MARAPUR-MBR®, UF, RO, BIOPUR® and spent caustic treatment.

Treated effluents, along with cooling tower and boiler blowdown streams, are further processed in an RO-based demineralization plant for sustainable and cost-efficient water recycling.”

Project Features:

• Scope: Design, Engineering, Procurement & Supply, Supervision of Installation, Commissioning and Testing at site.
• Technologies: WABAG has installed advanced multi-stage treatment systems including innovative WABAG technologies:
• • SBR for RWTP
  • API, CPI & DAF
  • Biotower
  • MARAPUR-MBR® – Membrane Bioreactor
  • Ultrafiltration
  • Reverse Osmosis
  • BIOPUR® – Biofiltration
  • Dual Media Filtration
  • High Pressure and High Temperature Wet Air Oxidation
  • Bioremediation for Oily Sludge
  • Thermal Oxidiser for Offgas Treatment
  • RO Reject treatment
  • Carbon adsorption for VOC gases
  • Sludge thickening and dewatering.
• Impact: This comprehensive water management solution ensures the supply of industrial water for refinery operations and the proper treatment of effluents from production processes by employing the most modern technologies to produce high-quality effluents. Additionally, a stream of treated effluents is further purified in a recycling system. As a result, 26.5 MLD of water can be reused as demineralized water in the refinery process, providing both economic and ecological benefits.
